6.02 x 1023<br> Significant figures
Bond [772]

Answer:

It depends on the number of significant figures you are changing to

Explanation:

6.02×1023=6158.46

1 sig fig = 6000

2 sig fig = 6200

3 sig fig = 6160

4 sig fig = 6158

5 sig fig = 6158.5

6 sig fig = 6158.46

When solving significant figures you have to consider the number after each number like in the case of changing to two sig fig the number following one is five and when the number is up to or greater than five you add a value of one to the number before it. But in a case where the number is less than five you just leave it like that like in the case of changing to one sig fig

A gas balloon has a volume of 106.0 liters when the temperature is 25.0 °C and the pressure is 740.0 mm Hg. What will its volume
ipn [44]

Answer : The final volume of gas will be, 103.3 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 740.0 mmHg  = 98.4 kPa

Conversion used : (1 mmHg = 0.133 kPa)

P_2 = final pressure of gas = 99.3 kPa

V_1 = initial volume of gas = 106.0 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 25.0^oC=273+25.0=298K

T_2 = final temperature of gas = 20.0^oC=273+20.0=293K

Now put all the given values in the above equation, we get:

\frac{98.4kPa\times 106.0L}{298K}=\frac{99.3kPa\times V_2}{293K}

V_2=103.3L

Therefore, the final volume of gas will be, 103.3 L

What is the frequency of a wave that has a wave speed of 20m/s and a wave length of 0.50m
wlad13 [49]

f = 40 Hertz

Explanation:

Velocity of a wave = frequency × wavelength

frequency = velocity/wavelength

20m/s = f × 0.50

20/0.50 = f

40 Hertz = f or f = 40 Hertz
